In high speed rotary web printing presses where quick drying inks and a web heating and cooling unit is employed, it is very desirable that the printing and webheating and cooling units 5 be so located with respect to each other as to produce the best results while occupying a minimum amount oi space.

My invention comprises, generally, a printing unit located at one end of the press, a combined 1'0 heating and cooling unit located at the opposite 20 My invention more particularly comprises an 01 my invention; and

Fig. 3 represents a similar view oi. a third forn of my invention.

The printing unit which is located at one end 7 35 of the press is herein represented as a live color unit, the impression cylinder being denoted by i and the two form cylinders on one'side oi the impression cylinder by 2, 3, and the three i'orm cylinders upon the other side of the impression 4 cylinder by l, 5, 8.

The inking mechanisms for the form cylinders are denoted by 29, la, la, 50, 8a. a

The combined heating and cooling unit which is located at the opposite end 01' the press is herein represented as comprising a large heating cylinder I and-two small cooling cylinders 8, 9, said cooling cylinders being located between the printing unit and the heating cylinder of the com-- bined heating and cooling unit. This combined 50 heating and cooling .unit is located in line with both the printing unit and the combined heating and cooling unit and beyond the printing unit, to and through the printing unit and from thence to and through'the combined heating and cooling unit. In this form the web is delivered at the end 01' the press opposite to that occupied by the web supply roll and in a path passing under the heating and cooling unit.

In the form illustrated in Fig. 2 the web is led from the supply roll in which, in this instance. is 10 also located below the printing and combined heating and cooling units and at the opposite end oi the press from the printing unit, to and through the printing unit and from thence to and through the combined heating and cooling unit.

.In this form the web is delivered at the same end of the press as that in which the web supply roll is located and in a path passing under the heat ing and cooling unit.

In the form shown in Fig. 8 the web supply roll is located below and at the opposite end of the press from the printing unit and the said heating and cooling unit is located above the printing unit. In this form the web is led to and through the printing unit and from thence to and through the combined heating and cooling unit. From thence the web is delivered at the same end of the press as that occupied by the web supply roll and in a path passing under the heating and cooling unit.

It will be under that guide rolls are provided for passing the web in the prescribed paths from the web supply roll "I to the delivery.

It will also be understood that any suitable heating medium, such as steam, may be supplied to the heating cylinder 1 and that any suitable cooling medium, such as water. may be supplied to the cooling cylinders 8, 9.

It will also be understood that any well known or approved quick drying inks may be in the 0 printing unit.

What I claim is:

1. In a multicolor rotary printing press, a printing unit located at one end of the press. a

combined heating and cooling unit located at the 4s opposite end of the press and a web supply roll, all located in line with the press, and means for leading the web through the printing and combined heating and cooling units and delivering the web at the opposite end of the press from the so printingunit, the said printing unit comprising an impression cylinder; and, live form cylinders arranged around the same.

2. In .a multicolor rotary printing press. a printingunitlocatedatoneendotthepresaa ss combined heating and cooling unit located at the opposite end of the press and a web supply roll, all located in line with the press, and means for leading the web through the printing and combined heating and cooling units and delivering the web at the opposite end of the press from the printing unit, the said printing unit comprising an impression cylinder and live form cylinders arranged-around the same, two form cylinders upon one side and three form cylinders upon the other side of the impression cylinder.

3. In a multicolor rotary printing press, a printing unit located at one end of the press, a combined heating and cooling unit located at the opposite end of the press, and a web supply roll, all located in line with the press, thecombined heating and cooling unit being located above the printing unit and the web supply roll being located below the printing unit, and means 'for' leading the web through the printing and combined heating and cooling units and delivering the web in a path passing under the heating and cooling unit at the end of the press where the web supply roll is located, the said printing unit comprising an impression cylinder and five form cylinders arranged around the same.
